本文研究拉格朗日子流形的平均曲率流。特别地,我们证明了如下的全局存在性和收敛性定理:如果T2n中的Lagrange图的势函数是凸的,则流始终存在,并且光滑收敛到平坦的Lagrange子流形.我们还讨论了保证全局存在性和收敛性的势函数的各种条件。
This article studies the mean curvature flow of Lagrangian submanifolds. In particular, we prove the following global existence and convergence theorem: if the potential function of a Lagrangian graph in T 2n is convex, then the flow exists for all time and converges smoothly to a flat Lagrangian submanifold. We also discuss various conditions on the potential function that guarantee global existence and convergence.
